Hydrogel-based flexible electronics

Apr 11, 2023 (Nanowerk Spotlight) Flexible electronics, which can maintain their functionality under various conditions such as bending, rolling, folding, or stretching, have seen significant advances in recent years. These electronics have expanded into a wide range of applications, including flexible sensors for monitoring physical and chemical changes, energy harvesting...

Stripes within crystals hint at behavior of electrons in quantum systems

Apr 10, 2023 (Nanowerk News) Hidden stripes in a crystal could help scientists understand the mysterious behavior of electrons in certain quantum systems, including high-temperature superconductors, an unexpected discovery by RIKEN physicists suggests (Proceedings of the National Academy of Sciences, "Correlation-driven electronic nematicity in the Dirac semimetal BaNiS2"). The electrons...

Single molecule studies of quantum dot

Apr 10, 2023 (Nanowerk Spotlight) The research groups of Prof. Ying Hu and Prof. Preston Snee of the UIC chemistry department have reported single molecule studies of energy transfer using a quantum dot donor with an organic dye acceptor. Semiconductor quantum dot-dye conjugates such as shown in Figure 1(A) are...

Modeling longer-lived holes in silicon quantum dots

Apr 10, 2023 (Nanowerk News) A theoretical model developed by three RIKEN physicists for optimizing semiconductor nanodevices will be helpful for scaling up quantum hardware (Physical Review Letters, "Charge-noise-induced dephasing in silicon hole-spin qubits"). An electron trapped in a semiconductor device offers a promising building block for future quantum computers....

Engineered plants produce sex perfume to trick pests and replace pesticides

Apr 10, 2023 (Nanowerk News) By using precision gene engineering techniques, researchers at the Earlham Institute in Norwich have been able to turn tobacco plants into solar-powered factories for moth sex pheromones (Plant Biotechnology, "Tunable control of insect pheromone biosynthesis in Nicotiana benthamiana"). Critically, they’ve shown how the production of...
